The goal lifted the Terps to a weekend sweep of the Scarlet Knights.
All four Maryland goals resulted from penalty corners.
Scarlet Knights' coach Meredith Civico was one of the pieces to Maryland's 2005 national championship-winning side.
The Terps tallied 13 shots but were shutout Sunday.
Despite outshooting the Wolverines 13-6, the Terps couldn't find a goal.
Wolverines goalkeeper Anna Spieker made five saves.
The Terps had been tough to break down, conceding few chances in matchups against the Big Ten's best teams.
The goalkeeper pitched a shutout in the Terps' win over the No. 2 Hawkeyes on Friday.
Maura Verleg buried the winner in the 3rd quarter.
The Terps and Hawkeyes have met many times over the years, perhaps no time more dramatic than their NCAA tournament clash in 1999.
